Parish, Newton, iowa, assigner to Automatic Washer Company, Neon, iowa, a corporation oi Delaware Application October 19, 1936, Serial No. Nihil@ 3 Claims. 1(61. 68253) This invention relates to a roll wringer and particularly to a power driven wringer with a power reset mechanism.

The development of the modern electric washer accentuated the need for an effective, safe and convenient wringer of attractive design. As a matter of fact, in a large percentage of the cases, the Woman purchaser rst examines the wringer on the electricv washer she is considering for purchase. From the above facts it is obvious that the design and performance of the wringer is highly important.

In the development of wringers for the modern electric washer, it has become apparent from4 experience that although attractive designs, safety release and effective performance are important, it is even more important to maintain simplicity oi' operation, in order to avoid ex pensive diiculties 'resulting from even minor complications of operation. l

The modern wringer, above everything else, must operate simply and naturally, so that the average operator will have no diiiiculty in operating it.

'I'he particular object of. my invention is to provide a wringer that is attractive in appearance and simple in operation.

Another object is to provide a wringer that .ner to assure safe operation at all times.

Other objects and benets will be disclosed by the following descriptions and illustrations of which:

Now referring to Fig. l. The numeral 20 indicates vthe lower frame complete; ,the numeral 2| shows the hinged top frame; 22 is the lower roll and 221s the upper roll.

The upper frame 2l hinges on the pin 2l xed in the frame 20. The upper roll 23 is mounted in bearings 25 and 26 attached to the upper frame as shown.

The lower roll is mounted in bearings 21 and 28.

vThese bearings are best shown in Figs. 4 and 5 the rolls, cam bar and spring mounting correis deemed` that the structure is well understood,

no pertinency in the present'invention and will,

therefore, not be described.

'I'he coupling 3| attaches to a vertical drive shaft from the washing machine drive gear case located under the washer tub. The wringer is pivotally mounted on a tube supported on this Vgear case and extending upwardly through the holes 32. The wringer mechanism is driven through the copling 3|, shaft. and the bevel gears 34, 35 and 36.

A jaw clutch 31 slidable on a hexagon sleeve 29 is movable sidewise to engage clutch jaws on the inside of the pivotal gears 35 and 36 to cause rotation of the shaft 29 in one direction or the other. It is obvious that when the clutch 31 is in the central position as shown in Fig.` 1 there will be no rotation of the shaft 29. The clutch 31 is actuated by the rotation of the handle 39 through the vertical shaft as on the end of which is a pin eccentrically mounted contacting the groove in the clutch 31 to cause the clutch 31 to slide along the sleeve 29' when actuated by the handle 39.

The gear nest is mounted in a recess in the frame and is secured in said recess by the cover plate 40 with cap screws as shown.

By this structure I am enabled to retain a quantity of grease in the recess to provide lubrication of the gears and other parts.

Onthe inner end of the shaft 29 is mounted the coupling member 42. This member 42 is ro- Through a hole in the top of the frame zo is mounted a control button 53` normaly retained in position by the spring detent ball 54 contactving in two grooves as shown. Between a shoulder on the lower end of the shaft 53 and pin 55 is mounted the bifurcated link member 59 and the cross web of the member 48. The hole in cross web 48 is elongated to permit pivotal movement of member 48 'around the pin 49. The link 59 is pivotally connected with another bifurcated lever 60 which is pivotally mounted on the frame 20 by the pin 6|, The cross member 62 of the bifurcated lever 68 is positioned to contact the lock pin 63 which is normally held in down position by the compresion spring 64 against the cotter pin 65. The pin 66 on the top of the lock pin 63 with the washer 61 contacting the forked opening in the positioning lever 69 which is pivotally supported by the cross pin 68 provides a mechanism whereby the lock pin 63 may be raised when the positioning lever 69 is lmoved inward.

A cam bar 10 is rotatably mounted in bearings in the frame 20. The cam faces. 1| best shown in Figs. 4 and 5 provide means whereby pressure is created between the rolls upon. rotation of the shaft 10.

Now referring to Figs. 2, 3, 4 and 5, it will be noted that dual lever member 12 is fixed on the shaft 18 with pins 13 and 14 extending in opposite directions from the face of the lever member 12 to engage slotted openings 15' and 16 in levers 15 and 16. These levers are pivotally mounttatable on shaft 29 but may be fixed for rotation i therewith by the ball 43 in the recess ball groove 43. in a manner that will later be described in detail.

- A clutch sleeve 4|.is slidably mounted on the coupling member 42 in a manner to cause the ball 43 to be retained in the ball groove 43' when in one position and to allow the ball 43 to come out of the ball groove 43 when in the opposite position.

A compression spring 44 is mounted between the end of the slideable clutch member 4| and the emerged end of the coupling member 42. This f compression spring normally tends to move the clutch member 4| toward the gear head, the purpose of which will later be described in de- In a hexagonal recess in the end of the coupling member 42 is yieldably mounted a coupling member with e. central hole to t the drive tang 41 of the upper roll 23. The spring 46 allows the drive member 45 to move inward. under conditions where the tang 41 is not positioned to enter the mating hole in the member 45.

A bifurcated clutch actuating stamping 48- is pivotally mounted on a pin 49 supported in the frame 20. In the lower ears of this bifurcated stamping 46 are pins 56 which enter the groove 4|' of th'e clutch 4I to cause the clutch 4| to slide when the stamping 48 is pivoted about the pivot pin 49.

ed on a pin 11 fixed to a cross member of the frame 29. Large dogs 18 and 19 are pivotally mounted on the member which is also supported on the pin 11. These dogs are tensicned outwardly by tension spring 2| as. shown.

Two other springs 82 and 83 attach to the le'- vers 15 and 16 in a manner to 'normally cause these levers to be held outwardly `against pins 84 and 85 as shown.

Fixed latch ledges 86 and 81 on the frame 2| are positioned to engage the latch dogs when the member 80 is rotated in a manner as shown in Fig. 3.

Now referring to Fig. 4. Note the cam bar 10 bearing on the cross member of 88. Into this cross member are screwed flanged studs 89 which support compression springs 90 between .the fianges of the studs 89 and the bearing member 28. It will be noted that adjustment for the springs is provided by screw driver slots in the bottom of the studs 89.

In Fig. 5 we have shown the same parts as they are affected by 90 rotation of the cam shaft 10. As a result of the operation of the cam surface 1|, the cross member 88 is lifted and with it the studs 89 carrying the springs 99 thus putting the rolls 22 and 23 under pressure with each other.

Now referring to Fig. 6, it will be noted that the upper frame 2| is in lower locked position and the clutch member 4| .is in operating position with the key ball 43 engaged in the slot 43'.. The button control plunger 53 is in its highest position and so held by the detentball 54.

The interlock control links 59 and 66 have been actuated to bring the cross member 62 on top of the lock plunger. With'the parts in the position described, the wringer is in operation with the rolls rotating and the wringer locked on the wringer post. With the partsin this position it is obvious that if the operator would lowerthe control button 53, rotation of the rolls would be stopped by the sliding of the clutch member 4| rotate without rotating member 42. Simultaneously the interlock levers 59 and $0 would be actuated to raise the cross member 62 away from the lock pin i3 thus allowing the wringer tobe positioned by means of the positioning lever il.

In Fig. 'I we have illustrated what occurs when the top frame is raised. The cam surface 52 has rotated about the pin 24 against the cam shoe il which has actuated the clutch lever 48 to cause the clutch 4| to slide to the lett and disengage the drive ball 43 from the drive slot 43'. Thus the rotation of the rolls is stopped and will remain stopped until the operator raises the control button-53. It will be understood that the detent ball 54 engaging in the grooves of the pin I3' is sumcient to hold the parts in position against the pressure of a spring ee.

Now referring to Figs. 8, 9 and 10, I'show the action of the power reset drive mechanism. In Fig. 8 the lug on 42 has just startedto engage the pin 80' at the beginning of the power stroke. It will be noted that thepin 8S' is in its lowermost position in the slot B".

In Fig. 9 the power stroke has progressed to the point where the lug on 42 is just passing the pin 80'. It willl be noted that in this position the pin 8o' has been forced to the highest position in the slot 80".

In Fig. 10 I show the relation of the lug on 42 with the pin 8o' after the power strokehas been completed. It will be noted that the pin 80 has now dropped to the lowest position in the slot 80 and thus provides clearance with the drive lock on 42.

erator to center the release mechanism s4 ln order to accommodate the above action.

' their relation to each other, the operation of the wringer will be understood.

(a) Assuming the wringer in operation, with the parts in the relation as illustrated in Fig. 1.

In Figs. l1 and 12, I have shown the relation w of the parts of the lockand release mechanism. A U-shaped stamping 9| is rotatably mounted on shoulder studs 92 attached tothe roll bearing supports. A cross clip 93 is attached to 8l near its outer end and into this cross clip on each side *are riveted release buttons 94 which extend through holes 2 I' in the upper frame 2l.

The lock member 95 is pivotally mounted by the pin 96 and is urged outwardly about the pivot $6 by the spring 91. 'Ihe lock 95 reduces in cross sectional area toward the top and is slightly depressed downward with the end 9i' for a purpose which later will be explained.

Slotted openings 93' on each side of a narrow center section in the members 9| and 93 are positioned .to permit the escape of the tail end of the lock 95 through the openings 93' thus permitting the upper frame to be unlocked as shown in Fig. 14.

It will be noted that the depressed section 95' on the lock 95 prevents the lock from slipping through the slots although permitting sufficient movement for the unlocking action.

It will be obvious that the upper frame may be unlocked by exerting slight pressure on the release button 94 which 4rresults in the tilting of the member 9| which causes the unlocking action. This condition is clearly illustrated in Fig. 13.

A lower lock member 9,8 and an inwardly tapered stamping 89 are riveted to the frame 20 at a point just under the lock member 95 on the up- 2l the inwardly tapered member. will cause thev lock 95 to be forced outwardly and thus engage the stationary lock 98 as shown in Fig. 12. Under the following functional conditions will be observed.

The wringer may not be unlocked from the wringer p ost for rotation because the interlock levers prevent the lifting of the lock pin 63.

(b) Rotation of the wringer rolls may be stopped by depressing the control button 53. When the rotation of the rolls is thus stopped, the Vlock pin 63 may be lifted and the wrlnger positioned as desired. i

(c) The wringei` may be immediately unlocked by pushing the release -button @d which actuates the release mechanism and allows the upper frame to be swung upward aboutv the pivot 24 by roll pressure.

(d) When the release knob 94 is operated to release the latch 95 to the position shown inliigure 7 by the pressure of the lower roll on the upp'er roll, the part It and the lower roll then return automatically to thepo'sition shown in Figv cient to eiect the disengagement.

(e) By this 90 rotation of the shaft 10 and cam and the separation of the rolls effected as illustrated by Figs. 4 and 5.

(I) When the top frame is again depressed into locked position and the vtang 41 of the shaft 4B is engaged in the drive member 45, then the operator may reset the roll presure by lifting the button 63 thereby reengaging the clutch and establishing driving relationship with the lug on mem- 'bErlL (g) It is obvious that during all of the above tuated from forward to reverse and neutral by the lever 39.
